Munuo was the first female Judge of a Court of Appeal in East Africa.
[2] Munuo spoke about the number of rape cases that failed due to bribery of doctors by accused persons.
[4] She also spoke out against the patriarchal system that denied capable women from being appointed as judges across Africa[5][6] and against sexual corruption and "sextortion".
[9] She noted in 2014 that delays in the judicial systems impacted significantly on poor people, particularly women, whereas female representation in the judiciary had encouraged women to study law and join the legal profession.
[1] In 2016, Munuo co-authored a book titled A Comparative Review of Presidential Election Court Decisions in East Africa with legal scholars Frederick Ssempebwa, Businge Kabumba, and Lillian Tibatemwa-Ekirikubinza,[11] in which they suggest the Supreme Court of Uganda should have cancelled the re-election of President Yoweri Museveni after the 18 February polls breached electoral laws.
